I have the Takuma v100 and a LF Happy foil, so not a comparison to the Impulse but:
-Takuma is WAY more stable and slower and comes up on foil instantly, great for surf foiing and kitesurf foiling
- Happy foil is much much faster and more fun for kite foiling in my opinion but would be bad for kitesurf foiling

Impulse is supposed to be in the middle so probably an awesome foil but I'm just guessing.
